GE dishwasher upper-rack roller WD12X27578: verified fit

GE lists WD12X27578 as the replacement for WD12X22829 in the exact upper-rack assemblies for three full model strings: GDF510PGJ6WW, GDF535PSR5SS, and GDT630PYM4FS. It separately lists 2-wheel brackets for the GDF models and a 3-wheel bracket for GDT630PYM4FS; each model also has a distinct full rack number. This is a narrow three-model fit matrix, not universal GE fitment.

Safety boundary

  • Empty the upper rack and use the appliance's exact Owner's Manual for normal rack handling and removal/reinstallation.
  • Do not force a binding rack or remove dishwasher panels for this part lookup. Stop and contact GE/authorized service if the rail, bracket, clip, or rack is bent or if the label does not match one of the exact model strings.
  • This record does not provide a wheel-specific replacement procedure.
Part typeDishwasher upper-rack roller

Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.

Models explicitly covered

These model identities have the source evidence listed below. Read the part decision and suffix limits before ordering.

Required identifiers

  • Complete GE parts model: GDF510PGJ6WW, GDF535PSR5SS, or GDT630PYM4FS
  • Original rack roller shown as WD12X22829
  • GE-listed replacement roller: WD12X27578
  • Distinguish the roller from each model's separately listed rack bracket, roller-and-stud assembly, and complete upper rack

Compatibility rules

  • GE's exact model assembly diagrams for GDF510PGJ6WW, GDF535PSR5SS, and GDT630PYM4FS each list roller WD12X22829 as no longer available and WD12X27578 as its replacement.
  • GE's GDF510PGJ6WW and GDF535PSR5SS diagrams list the separate 2-wheel bracket WD12X22802; the GDT630PYM4FS diagram lists the 3-wheel bracket WD12X22801.
  • The exact-model diagrams list different complete upper-rack supersessions; do not treat WD12X27578 as a full rack or bracket.
  • No model beyond the three exact part-list headings is covered by this matrix.

Never assume

  • WD12X27578 fits all GE dishwashers or every GDF/GDT family revision.
  • The roller includes a bracket, stud assembly, slide, locking clip, or complete upper rack.
  • The 2-wheel bracket and 3-wheel bracket are interchangeable.
  • An Add to Cart label or displayed price proves current delivery availability.

Three exact GE model receipts

  • GDF510PGJ6WW: position 682 WD12X22829 replaced by WD12X27578; 2-wheel bracket WD12X22802 and complete rack WD28X22626 → WD28X35779 are separate.
  • GDF535PSR5SS: position 682 WD12X22829 replaced by WD12X27578; position 683 separately names WD12X27578; 2-wheel bracket and whole rack are separate.
  • GDT630PYM4FS: position 682 WD12X22829 replaced by WD12X27578; 3-wheel bracket WD12X22801 and complete rack WD28X24438 → WD28X35778 are separate.

Exact-model fit is separate from stock

The exact GE diagrams support the model-to-part mapping. Current price/Add to Cart and temporary stock notes are time-sensitive and are not included as fit evidence or a delivery promise.

The GE model codes are limited to these full strings; similar family labels or other suffixes require a separate GE diagram lookup.
